New Nirvana Tracks Coming to Rock Band

The tracks are part of the "Celebrating Nirvana Pack," which is being released as part of the 20th anniversary of Nirvana's 1991 album Nevermind.

Since Nevermind is already available as a Rock Band download, the album's ten existing tracks will receive Pro Guitar/Bass upgrades, allowing the tracks to be played with Rock Band 3-compatible Pro Hardware.

The "Celebrating Nirvana Pack" includes the following songs:

"Heart-Shaped Box"

"Rape Me"

"All Apologies

"You Know You're Right

The tracks will be available on PS3, Xbox 360 and Wii for $6.99, which translates to 560 Microsoft Points or 700 Wii Points.

If you want to purchase the tracks individually, they're $1.99 each, or 160 Microsoft Points/200 Wii Points. A Pro Guitar/Bass upgrade is also available for "Heart-Shaped Box" for an additional dollar (100 Wii Points/80 Microsoft Points).

The tracks will be available on all platforms starting on September 20.
